About Chapter 8
- Chapter 8 part 2 section O5 is all about protecting workers and vehicles that have to work on high speed roads, although it recommends the same specifications be used for works vehicles on all types of highway irrespective of speed limit.
- It requires on high-speed roads, that all vehicles stopping on the highway for works purposes or inspections shall be equipped with high visibility rear markings.
- Permitted markings include chevrons comprising alternate strips of fluorescent orange-red retroreflective material and fluorescent yellow non-retroreflective material.
- Each strip of the chevron must be not less than 150 mm in width, inclined at 45-60° to the horizontal and pointing upwards.
- An alternative to chevrons is a solid block of fluorescent orange-red retroreflective material.
- Red retroreflective tape must also be applied to all rear facing edges of open doors, guardrails and equipment lockers, and to the face of any device that obscures the markings and is displayed to the rear and other road users.
- The reflective markings must be 'Class RA2' or 'microprismatic' (e.g. 3M™ Diamond Grade™ DG³ reflective sheeting) in the case of rear markings and 'high visibility fluorescent or non fluorescent yellow reflective' in the case of side markings.
- Conspicuity markings can reduce accidents, can save lives and improve the visibility of the vehicle
- Fewer accidents mean less downtime, less contracts missed and savings on repair costs
- Protect your company against potential legal action related to third party safety
- Reassures and motivates the workforce to know that your business takes their safety seriously
- To meet the highly recommended best practice guidance of TSM Chapter 8

50mph road, permanent speed and can be single lane.
What is the legal remit of chapter 8?
Chapter 8 is not a code of practice but the principles are the same. It is guidance based on best practice. Organisations need to show that they have considered Chapter 8 if they choose not to comply and have a good reason why they have chosen not to comply. A justification of non compliance needs to be documented. There needs to be a common sense approach to Chapter 8 from organisations.
Which parts of the UK are covered by Chapter 8?
The conspicuity section of Chapter 8 is consistent for the UK and Northern Ireland.
Is there an overlap between regulation ECE104 and Chapter 8 chevrons?
You would need both to apply both chapter 8 and ECE104 markings if the vehicle is over 7.5 tonnes or trailer over 3.5 tonnes and are expected to stop on a high speed road. Chapter 8 states: “O5.2.7 Motor vehicles with a maximum gross weight exceeding 7.5 tonnes and trailers with a maximum gross weight exceeding 3.5 tonnes must be fitted with rear markings in accordance with the Lighting Regulations.
